Abstract: A phototriggerable composition and method for use in crosslinking protein such as collagen comprising application of a tethered diazopyruvate composition followed by irradiation, whereby the composition results in the sutureless wound closure of, for example, a tendon or cornea.

Abstract: Apparatus and methods for generating an image of an object utilize a scannable microlaser array to provide a flying spot light source. The microlaser array is scan-energized and imaged onto the object to illuminate the object. Light scattered, reflected, or transmitted from the object is collected and detected, and can be converted to a video-level signal for display on a monitor. The microlaser array can be raster-scanned, scanned in a random access mode, or have at least two laser elements energized simultaneously, to enhance contrast, provide multiplexing, and increase dynamic range. A confocal configuration utilizes a detector array that is scan-read synchronously with the laser excitation pattern.
